Abstract While sodium‐ion batteries (SIBs) represent a low‐cost substitute for Li‐ion (LIBs), there are still several key issues that need to be addressed before SIBs become market‐ready. Among these, one of the most challenging is negligible sodium uptake into graphite, which keystone present LIB technology. Although hard carbon has long been established as best substitutes, its performance remains below graphite in LIBs and storage mechanism under debate. Many other carbons have recently...
We present an overview of the main techniques for production and processing graphene related materials (GRMs), as well key characterization procedures. adopt a 'hands-on' approach, providing practical details procedures derived from literature authors' experience, in order to enable reader reproduce results.
Deep eutectic solvents (DESs) have been used in the synthesis of nitrogen-doped carbons exhibiting a hierarchical porous structure. The CO2 sorption capacity these solid sorbents was extraordinary because their relatively high nitrogen content and bimodal structure where micropores provide surface areas (ca. 700 m2 g−1) macropores accessibility to such surface. DESs were composed resorcinol, 3-hydroxypyridine choline chloride 2 : 1 molar ratios. Polycondensation resorcinol (with...
Deep eutectic solvents are a new class of ionic liquids obtained via the complexion quaternary ammonium salts with hydrogen-bond donors (such as acids, amines, and alcohols, among others). The charge delocalization that occurs through hydrogen bonding between halide anion hydrogen-donor moiety is responsible for decrease in freezing point mixture, relative to melting points individual components. We have recently reported on use deep suitable solvents, carry out polycondensation...

Synthetic approaches based on deep eutectic solvents allow the preparation of phophate-functionalized carbon monoliths with a hierarchical structure. Both functionalization and hierarchy—combining macropores high surface areas while preserving monolith densities—are critical for ahievement remarkable energy densities in supercapacitor cells.
